This essay will be looking in two types of lexicon search models; serial search model and a direct access model both models hold different assumptions on how words and information are found but, the true measure of how adequately each model accounts for what the human brain does through a neural network, is how well it can provide an account for experimental findings in word recognition. These include; the frequency effect, the non-word effect, priming and spreading activation. Firstly, what is meant by serial search and direct access model? The two models in question are described as lexical instance models termed by Carr and Pollatsek (1985) this commonality describes that they simply use perceptual access to the lexicon where, research has shown the attributes of an individual word are stored. The first search model is the serial search model by Forster (1976) which is comparable to searching for a topic in a textbook. Firstly you look at the index to search for the word this is access file which points you in the direction of which page the topic is located on in the book, the page...
